too true, the T1 looks like a monster.... P3D is a better carrier by far, and it WILL be able to slip into pockets, where i doubt the t1 will..

The T1 isn't that big in person, somehow it looks bigger in pics. In fact I've carried it easily without its holster in the front pocket of my jeans. It's also fairly nice to carry in its holster on a belt.
Those who say it's too big have to realize that they are comparing lights without significant reflectors with lights (the Fenix T1 but also something like the Lumapower M1, which I also have, and perhaps the Huntlight judging from pics) with significant but still not huge reflectors. Obviously, the reflector adds heft, but also gives you quite a bit--a much better shape and throw for your light output.
The T1 is a big heavier (but still not enormously so) because of the effort to make it tough and the steel bezel. Naturally, if you don't want or need these attributes, another light would serve your needs better.
Another way to think about it is that the Fenix T1, like the Lumapower M1 are designed more to be outdoors lights, and P2D/L1D Rebel 100 are more in an EDC formfactor, and the P3D Rebel 100/Q5 is a bit of an intermediate light, bigger than an EDC but smaller than the outdoors lights like the T1 and M1. So it is a bit unfair to compare the T1 with the P3D and declare the T1 too large.
Maybe it's more correct to say that the T1 is OK for an outdoors light, but the P3D is too large for an EDC! In fact, the best use for the P3D in my opinion is as a bike light! You can fit it onto the Fenix bike flashlight holders as well (or two of them at the same time!) and there their shape and relative light weight is a big advantage.
